Overview
PZT piezo ceramics can be used for a wide range of industries such as modern communications, radar, sonar, automatic measurement and ultrasonic sterilization, ultrasonic power and so on.
    
1) PZT4 materials: ~<a href="http://www.piezo-ultrasonic.com/piezoelectric-ceramics.html" target="_blank">PZT piezo ceramics </a> have a double behavior of receiving and transmitting, with higher sensitivity and lower dielectric loss.

2) PZT5 materials: PZT piezo ceramics of receiving type have higher electro-mechanical coupling coefficient, with moderate dielectric constant and higher sensitivity.

3) PZT8 materials: PZT piezo ceramics of high power transmitting type have good piezoelectric property, high mechanical strength, high coercive field, low dielectric loss in strong fields.
